i’m sorry but you cant make a micro:bit vibrate. i tried to use an extremely low frequency but that didnt work.

Hi @maijin658 , Welcome to the forum!

If you have a servo motor or regular motor that you can easily connect to the micro:bit, you can probably get it to vibrate some by moving the servo/motor back-and-forth quickly.

There are a few kits that include vibration motors or haptic feedback, like:

Here’s an instructable that shows one way to connect a vibrating motor to the micro:bit: https://www.instructables.com/CalmCuff/ HOWEVER, the micro:bit isn’t able to supply enough current to activate many motors in this way. It may not work or not work well. Many micro:bit electronic kits include a transistor to control a motor, which is usually more reliable.

Here’s a previous forum post about this sort of topic too: Make Micro:bit vibrate remotely - #2 by bsiever

Good luck on the project!

i have never thought of external devices!
